Determination of arsenic, cadmium, copper, nickel, lead, zinc in lead ore for import and export - Inductively couple plasma atomic emission spectrometric method1 ScopeThis standard specifies the method for the determination of arsenic, cadmium, copper, nickel, lead, zinc in lead ores for import and export by inductively coupled plasma atomic emission spectrometry. This standard applies to the determination of arsenic, cadmium, copper, nickel, lead, zinc content in lead ores for import and export. The measurement range of each element is as shown in Table 1. Table 1 -- Measurement range of each element2 Normative referencesThe following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) are applicable to this standard.

The element emission intensity was measured by plasma emission spectrometer.4 ReagentUnless otherwise specified, the reagents used are all analytical reagents and above; the water is grade-2 water that meets the requirements of GB/T 6682. 4.1 Hydrochloric acid (ρ = 1.19 g/mL). 4.2 Nitric acid (ρ = 1.42 g/mL). 4.3 Nitric acid (1 + 9). 4.4 Lead standard stock solution. Accurately weigh 8.00 g of lead nitrate; use 400 mL of nitric acid (4.3) to dissolve it; transfer it into a 1000 mL volumetric flask; dilute to the mark; 1 mL of this solution contains 5 mg of lead. 4.6 Mixed standard solution. Pipette each element standard stock solution (4.5) into a 100 mL volumetric flask; use nitric acid (4.3) to dilute it to the mark; mix well. The amount of each tested element in 1 mL of this solution is as shown in Appendix A.5 Instrument5.1 Inductively coupled plasma atomic emission spectrometer.6 SpecimenThe specimen is passed through a 149 μm screen and dried in an oven at 60 °C for 4 hours; then placed in a desiccator to cool to room temperature to prepare for use.7 Analytical procedures7.1 Pre-treatment of samples Weigh about 0.2 g of sample, accurate to 0.0001 g. Place it in a 250 mL beaker. Use a small amount of water to wet it. Add 10 mL of hydrochloric acid (4.1). Leave it at room temperature for about 30 min. 7.2 Determination 7.2.1 The analytical line is as shown in Table 2. 7.2.3 Introduce the sample solution to be tested into the plasma in turn, to respectively measure the spectral intensity at the analytical line of each tested element.8 Calculation of analytical resultsCalculate the mass fraction of the measured element according to formula (1); the value is expressed in %.9 Precision8 laboratories conduct method precision tests on 7 levels of samples and perform statistics in accordance with GB/T 6379.2.The results are as shown in Table 3.
